Interior architecture is the main factor in creating pleasant environments for in-patient healthcare. Whether in paediatric or geriatric wards, economic efficiency, patient well-being and staff satisfaction are increasingly the focus of treatment, healing and healthcare concepts around the world. Well-designed interior architecture concepts for patient rooms can benefit the patient's process of recovery and, through its atmosphere and functionality, improve the quality of the hospital experience. This book explores the design of the patient room as a core part of healthcare environments. It describes the different design components, such as material, colour, light and surface finish, and addresses the needs of hygiene and the specific challenges presented by demographic change and digitisation, as well as workflow issues and economic efficiency. Fourteen international case studies illustrate these design principles.
